4N25-500E

Overview

The Broadcom Limited 4N25-500E is a single-channel high-speed optocoupler featuring a phototransistor output with base. It provides electrical isolation of 2500 Vrms and supports data rates up to 100 kb/s. The device operates within a temperature range of -55°C to +100°C and utilizes a 6-pin SMD/SMT gull-wing package. Key electrical parameters include a forward current of 80 mA, a collector current of 100 mA, and a typical rise/fall time of 3 µs.

Feature Summary

• Integrates an infrared emitting diode and a phototransistor with base for signal transmission
• Provides galvanic isolation between input and output circuits
• Supports surface-mount installation in a compact 6-pin package

Applications

• Industrial networking systems
• Electrical circuit interfacing across diverse voltage levels
• Signal isolation in measurement equipment

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific suffix matches the required lead-free and halogen-free specifications. Ensure the package type aligns with PCB footprint requirements. Check for obsolescence notices or lifecycle changes before finalizing procurement plans.

Selection Notes

Select this component when single-channel isolation with moderate speed is required. Consider the 2500 Vrms isolation rating for safety compliance. Evaluate the 100 mA collector current capability against load requirements. Compare performance metrics against alternative models if higher data rates are necessary.

Part Context

This part belongs to the 4N series of optocouplers manufactured by Broadcom Limited. It represents a standard industry design widely used for general-purpose isolation tasks. The 500E suffix typically denotes specific packaging and environmental compliance attributes distinct from other variants in the family.

Replacement Considerations

The 4N25-000E is a documented variant within the same product line. Verify pinout compatibility and electrical parameter equivalence before substitution. Cross-reference datasheets to ensure functional parity in the target application.
